Deal (2008)

Tommy Vinson (Burt Reynolds), a former cardsharp, gave up poker years ago when his wife threatened to leave him. Tommy finds a way to get back in the game when he meets Alex Stillman (Bret Harrison), an up-and-coming player who still has a lot to learn. Tommy strikes a bargain with Alex; he will pay the expensive entry fees to major tournaments if Alex will follow Tommy's instructions to the letter. However, a Las Vegas call girl (Shannon Elizabeth) soon threatens their profitable relationship.
